Pixel structure and liquid crystal panel

Abstract

The invention provides a pixel structure and a liquid crystal panel. The pixel structure comprises a pixel electrode, the pixel electrode comprises a main electrode, a branch electrode connected withthe main electrode and a sealing electrode surrounding the main electrode and the branch electrode, and at least one end of the main electrode and at least one end of the branch electrode are connected with the sealing electrode; a notch electrode is formed on the long side of the sealing electrode, extends into the pixel structure and divides the pixel electrode into at least two pixel subareas,so that one original pixel subarea is changed into a plurality of pixel subareas, the length-width ratio of the pixel subareas is reduced by utilizing a notch, a transverse main electrode is added inthe divided pixel subareas, the divided pixel subareas are divided into a plurality of pixel domains, the length of the branch electrode is shortened, the impedance of the pixel electrode is reduced,and the compensation capacity of the liquid crystal driving signal is improved, so that dark fringe abnormity of the whole pixel structure is avoided, and the display quality of the pixel structure isimproved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel structure and a liquid crystal panel. Background technique [0002] Usually, the liquid crystal display panel is composed of a color film substrate, a thin film transistor substrate, a liquid crystal sandwiched between the color film substrate and the thin film transistor substrate, and a sealant; its working principle is to control the liquid crystal layer by applying a driving voltage on two glass substrates. The rotation of the liquid crystal molecules refracts the light from the backlight module to produce a picture. The high vertical alignment liquid crystal driving method has the characteristics of high contrast, large aperture ratio and fast deflection speed of liquid crystal molecules. It is one of the key investment areas for TFT-LCD display panel factories in the mainstream market. [0003] HVA technology requires liquid crystal molecules to be negative liquid...

Problems solved by technology

[0005] The embodiment of the present invention provides a pixel structure and a liquid crystal panel, which can solve the problem that in the prior art, when designing the pixels of the VA liquid crystal panel, the metal traces occupy the pixel space, and the conventional design of the pixel electrode area below the color resistance area is a long and narrow strip. Shape, and the aspect ratio of the pixel electrode area is 3:1, it is easy to produce irregular liquid crystal dark lines, the original cross-shaped dark lines become irregular and distorted multiple dark lines, which increases the risk of abnormal alignment of liquid crystals, which seriously affects The use function of the LCD panel, the technical problem of impairing the pixel transmittance
